WILLIAM G. DUNHAM, F MAPLE HILL, CONNECTICUT, ASSIGNOR OF ONE-HALF TO WILLIAM J'. KEITH, 0F PROVIDENCE, RHODE ISLAND l HEAD FOR DISPENSING VESSELS` Specification of Letters Patent.

Patented Sept. 27, 1921.

To @ZZ whom z't may concern Be it known that I, WILLIAM G. DUNHAM,

. a subject of the King of Great Britain, re-

siding at Maple Hill, inthe county of Hartford and State of Connecticut, have invented certain new and .useful Improvements in Heads for Dispensing Vessels, of which the following is a specification.

My invention relates to the perforated discharging heads of dispensing vessels,- and has for its essential objects the prevention of accidental escape of the vessel contents through the perforations; the avoidance of exterior projections upon the head; facility o f operation; adaptability of the head for advertising purposes; sightliness of appearance; strength, and 'inexpensiveness My invention consists in the means and mechanism for providing the results above specified as hereinafter claimed.

In the accompanying drawings which constitute a part of this specification,

Figures 1 and 2 are a plan and side elevatiolrri. respectively of my dispensing head,

Fi l Figj4, a section on line 4-4 of Fig. 3, and

Fig. 5, a plan View of the device with the and disk removed. imilar reference numerals indicate similar parts throughout the views.

In the form thereof herein shown my device includes a cover 8 comprising a corrugated side 9 and a top 10 having an annular swell or shoulder 11 and a central depression or cavity 12. The top is provided with an annular series of holes 13. Exterior of this series there is an elevation or pin 14. A rotary disk or valve 16 has a central projection or depression 17 journaled inthe cavity 12, and is provided with an annular series of holes 18 equidistant from the latter projection and from the depression 17. These holes are spaced from each other the same distance as the spaces between the holes 13. Hence at certain times during the rotation of the valve the holes 13 and 18 register with each other. At dia-metrically opposite points exterior of its holes the valve has arcuate slots 20 and 21. The projection 14 registers slidably in the' slot 20.

3, an enlarged section on line 3 3 of A rotatable cap 23 is providedconsisting of a body 24 having a central depending projection 25 journaled in a cavity or depression 26 in the valve 16. The pivotal means 25 and 17 for the cap and valve are notl exelusive, as any otherconvenient means for centrally pivoting these two members to each other and to the body 10l may be employed, but the described means is most `efficient and economical. The cap 23 has a peripheral flange 28 loosely embracing the shoulder 11 and preferably provided upon its exterior with an annular series of corrugations as at 29. The cap body is provided with an annular series of openings of greater dimensions than the holes 18 of the valve. These holes may be of any preferred ornamental contour. In this instance certain of these openings, 31, are circular; others 32, star shaped, others 33, in the from of letters of the alphabet forming a name or legend. In the cap body 24 is also a depending projection, pin, or elevation 35 loosely registering in the slot 21.

The operation of the device is as follows. Assuming that the holes 13, 18, and the openings 31 are all in registration with each other, as shown in Fig. 3, the rotation of the cap 23 in the direction of the arrow in Fig. 4 throws the openings 31 out of registration with the holes 18 of the valve, and advances into contact with the valve 18at the end of the slot 21. The cap and valve thereupon continue to rotate together until the lower wall of the slot 21 engages the pin 14 of the Cover body, which operation throws the holes 18 and 13 out of registration, and thoroughly closes the top. The closed position of the parts is indicated in broken linesin Fig. 4.

The material of the valve 16 differs in color from that of the cap body 24. For instance, the cap .body may be of brass, and the valve may be nickel plated. 4In such case an attractive. contrast of color strikes the eye and the openings in the cap outline the desired ornamentation while at the same time performing their other functions.
